🔥Exothermic reaction
  • Any reaction that releases energy
  • Broad category of reactions
  • Includes neutralization and respiration
  • Negative enthalpy change
  • Does not require oxygen
🔥Combustion
  • A specific exothermic reaction
  • Reaction of a fuel with oxygen
  • Produces heat and usually light
  • Often forms carbon dioxide and water
  • Examples: burning wood, gas or fuel

Verdict

Combustion is one kind of exothermic reaction, requiring a fuel and oxygen. All combustion releases energy, but many exothermic reactions need no oxygen at all.

Frequently asked

Is all combustion exothermic?+

Yes. Combustion always releases energy, making it a type of exothermic reaction.

Are all exothermic reactions combustion?+

No. Neutralization and respiration release energy without being combustion.

What does combustion need?+

Combustion requires a fuel and oxygen, plus enough heat to start.
